Will it be at PCI E 3.0, right? inzone a c 251 U Graphics card May 8, 2012 9:24:16 PM Video cards do not fully fill up the bandwith of the Pci-e 2.0 slot or the Pci-e 2.1 slot so yes your card is maximized and it doesn't need the Pci-e 3.0 slot. ilysaml a c 143 U Graphics card May 8, 2012 9:24:23 PM Yes it. PCIE 2.1 is the same as PCIE 2.0 Quote:PCI Express 2.1 supports a large proportion of the management, support, and troubleshooting systems planned for full implementation in PCI Express 3.0. However, the speed is the same as PCI Express 2.0. bergami May 8, 2012 9:36:14 PM Best answer selected by bergami. Can't find your answer ? Ask !
